Dynamic Accuracy Test

This test applies to the following models:

Port 1 is always tested. Port 2 is only tested if Option 211 is installed.

There are two solutions for this test: a test-set only solution and a dual solution that can use either the test set or a function generator. The FieldFox firmware version will determine which solution can be used. TME will detect the firmware version of the FieldFox.

Test limits are related to the specifications for Corrected Measurement Uncertainty.

Test-set only solution

This solution can only use the Z5623A-H01 test set.

The Z5623A-H01 test set is used to measure dynamic accuracy of the A and B receivers down to -41 dBm. A reference power of -1 dBm is used for the test. Measurements are not made below -41 dBm because of noise interference at lower power levels.

Dual solution

With this solution, either the test set or the function generator can be used. The test set is the preferred method. Depending on the test equipment mapped, TME will determine the solution. If both the test set and function generator are mapped, TME will use the test set as the preferred solution. If the test set is not mapped, then TME will use the function generator solution providing that the function generator is mapped. Note that only the 33622A function generator is allowed for this test; no other function generator models are allowed. If neither the test set nor the 33622A function generator are mapped, the user will be prompted to map one of the solutions.

The test process prompts for a 30 minute wait to allow the temperature of the power sensor to stabilize. This wait may not be required if the power sensor is already stable.

  3. Only the 33622A function generator is allowed for this test; no other function generator models are allowed.

 

Connection Setups

The following notes apply to illustrations in the FieldFox Help:

  • Only a single representative model will be shown.
  • Some illustrations may differ than those in TME.

  • For procedures that apply to multiple ports, illustrations will show the setup on only one test port.

Preferred solution using the test set

 

Alternate solution using the function generator

For the two cables between the power splitter and attenuators, choose short but flexible cables. For best results, the cable between the attenuator on channel 1 of the function generator and power splitter should be of longer length than the cable from the attenuator on channel 2
